       pam_wtmpdb is a PAM module to record the login and logout information of the user. The module uses
       /var/lib/wtmpdb/wtmp.db as database file to store all information.

       Compared to some wtmp(5) implementations this PAM module is Y2038 safe and uses sqlite3 to store the
       information.

       Add the following line to e.g.  /etc/pam.d/login to display the last login time of a user:

                 session  required  pam_wtmpdb.so

       /var/lib/wtmpdb/wtmp.db
           Wtmpdb logging database file

       The session module type is provided for updating the wtmp database with the login and logout information
       about an user.
